Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention. The following example describes a case where a sale is made by reverse auction using the Internet, and a person having ordinary skill in the art applies the internet reverse auction method according to the present invention to a communication transaction using a public telephone network, a wireless communication network, and the like. Of course you can.

1 is a view showing the overall configuration of the reverse auction device using a communication network according to an embodiment of the present invention. The buyer terminal 106 is a computer of a person who purchases a service or a product through a website operated by the web server 100, and the seller terminal 108 is a service or a product from a website operated by the web server 100. The purchaser terminal 106 and the seller terminal 108 are connected to the web server 100 and the mail server 102 through the communication network 104.

The web server 100 is a seller rating data storage unit 112 for storing the seller rating data generated according to one or more evaluation items for a plurality of sellers, the importance of each evaluation item set by the buyer for the evaluation items Is stored in the importance storage unit 114 for each evaluation item stored in the evaluation item and the seller rating data based on the importance of the item by the control unit 110 for generating the seller-specific evaluation data for the buyer to select the seller for the buyer .

2 is a flowchart illustrating a procedure of performing a reverse auction method using a communication network according to an embodiment of the present invention.

The management company providing the internet reverse auction service selects a seller to be evaluated and an evaluation item (step 200), and prepares seller data for the selected seller according to the evaluation item. The seller data is graded according to predetermined item-specific grading criteria (step 202). Table 1 is an example of the evaluation items selected by the management company and the grading criteria for each item.

Evaluation item ＼ grading standard A B C D E Equity capital More than 15 billion 15 billion to 8 billion 8 billion to 3 billion 3 to 500 million Less than 500 million Company history More than 15 years 15 to 10 years 10 to 5 years 5 to 3 years Less than 3 years Sales scale 50 billion or more 50 billion to 15 billion 15 to 3 billion 3 to 1 billion Less than 1 billion Corporate form crape Enrollment Outer Etc Performance record 50 or more 50 to 40 40 cases-30 cases 30 cases-20 cases Less than 20

Table 1 is for sellers who provide services, and for sellers who provide goods, you can substitute work volume for sales. In addition, evaluation items and grading criteria set in Table 1 may be modified in other forms.

On the other hand, after preparing the seller data according to the evaluation item for the evaluation target seller selected by the company providing the reverse reverse auction service, the rating data for each evaluation target seller created according to the rating criteria for each item is shown in Table 2. It was. If Seller 1's equity capital is 20 billion won among the above-listed sellers, 'Equity Capital' is Grade A, if Seller 2's history is 4 years, 'Company History' is Grade D, and if Seller 3's sales is 1.5 billion won, 'Sales volume' is D grade, if the company type of seller 4 is external, 'enterprise type' is C grade, and if seller 5's 22 works, 'work performance' is D grade.

A buyer who wants to purchase a service or a product accesses the web server 100 of the company providing the internet reverse auction service through his purchaser terminal 106 and inputs the importance for each evaluation item that will be the basis of the seller selection. (Step 204).

In step 204, the web server 100 determines whether the shopper accessed by referring to the member information is a registered member of the website providing the internet reverse auction service, and registers the website with the buyer providing the internet reverse auction service. If it is not a member, it is preferable to further include the step of outputting a purchaser registration application for the buyer terminal unit 106, including the name, address, age, telephone number, occupation, e-mail address, and the like. However, it is desirable to enable the reverse auction service through the website regardless of whether or not the membership is registered, and it is desirable to encourage the subscription by providing services such as commission discount, mileage, etc. to reverse buyers. Do. In addition, when the buyer inputs the importance of each evaluation item, the buyer input information including the type of service or product to be purchased, the service implementation date or product delivery date, the service execution region or product delivery region, and the reverse auction bidding period. can do.

Table 3 is an example of an input form of importance for each evaluation item written in the form of a radio button, and the input form may be modified to another form such as a check button.

Evaluation Item 요 Importance Very important important usually Just then not needed Equity capital ○ ○ ○ ● ○ Company history ○ ● ○ ○ ○ Sales scale ○ ○ ○ ● ○ Corporate form ● ○ ○ ○ ○ Performance record ○ ○ ● ○ ○

The web server 100 generates the evaluation data for each seller participating in reverse auction by quantifying the seller rating data according to the importance of each evaluation item which is the basis for the seller selection input by the buyer in step 204 (step 206).

Table 4 numerically displays the importance of each evaluation item input by the buyer in step 204 according to a predetermined grade-specific grade score. The rating scores of importance for the above evaluation items are set to 10 for 'very important', 8 for 'important', 6 for 'normal', 4 for 'just so' and 2 for 'no need'. If so, in Table 3, the buyer set the seller's' capital size 'to' just so ', so the distribution is set to 4 points, the' history 'is set to' important ', so the distribution is 8 points and the' business type 'is' Very important ', so the scoring will be 10 points.

When the score of each grade is calculated with the highest score and the minimum score as 0, the score difference between each grade is calculated. In this case, since the distribution of equity capital is 4, the score difference between each grade is 1, the highest grade of A is 4, the grade of B is 3, the grade of C is 2, the grade of D is 1, and the grade of E is 0. The score for each rating item in Table 4 is calculated according to the above method.

Evaluation Item＼ Grade points A B C D E Equity capital 4 4 3 2 One 0 Company history 8 8 6 4 2 0 Sales scale 4 4 3 2 One 0 Corporate form 10 10 7.5 5 2.5 0 Performance record 6 6 4.5 3 1.5 0

Meanwhile, in step 202, the seller who participated in the reverse auction by the data ([Table 4]) digitized according to the grade score for the importance of the predetermined evaluation item that preset the importance of each evaluation item to be referred to the seller selection. Table 5 shows the rating data for each seller participating in the reverse auction, which digitized the seller rating data (Table 2). In Table 4, since the work performance is 6, grade A is 6, grade B is 4.5, grade C is 3, grade D is 1.5 and grade E is 0. Therefore, in Table 2, the performance of Seller 1 is Class B, so it is calculated as 4.5, which is the score corresponding to Class B of Table 4, and by the same method, Seller 2 is 0 points, Seller 3 is 4.5 points, Seller 4 is 4.5 points. Seller 5 scores 1.5 points.
